don't get 404's or some weird error messages

That's a start. Where all do you check for error messages?

Everything works as planned

- On which browsers?
- At which screen sizes?
- At which connection speeds?
- For disabled users?
- For search engines?

- What about ongoing site maintenance, especially if someone besides yourself needs to tweak something?
